I am aware that some ISPs block port 80 but when i change my server config to another port, i have problems with my site or localhost. Either the site is viewable and localhost is not or localhost viewable and site is not or both not viewable OR site is mostly viewable but not all pages load... any help?

Make sure you append the port at the end of the URL if you're using a port other than 80. You might be changing the console port instead of the web server port_________________Computer Programmer & Networking Specialist
